Specification of Letters Patent.

Application filed June 13, 1907. Serial No. 378,866.

Patented Apr. 11, 1911.

To all whom, it may concern:

Be it known that I, MATHIAS JENSEN, a subject of the King of Denmark,residing in Copenhagen, Denmark, have invented a new and ImprovedBottle-Filling Machine, of which the following is a full, clear, andexact description.

This invention relates to certain improvements in machines for llingbottles, cans, or other containers with liquid or semi-liquid`substances, and more particularly to that type of machine in which aseries of empty containers are continuously delivered to the machine,automatically filled in succession, and continuously delivered therefIOm. In a filling machine embodying all of the variousv features of myinvention, the containers are conveyed along an endless belt to themachine and the latter operates to remove them from the belt, fill themin succession, and return them to the belt. The machine is soconstructed that after filling each bottle, the liquid is removed fromthe bottle to a predetermined level below the mouth thereof,irrespective of slight variations in the height of successive bottles.

The invention consists in certain features of construction andcombinations of parts 'hereinafter described and more `particularlypointed out in theclaims.

Reference is to be had to the accompanying drawings, formin a part ofthis specification, in which simllar characters of reference indicatecorresponding parts in all the figures, and in which- Figure 1 is afront elevation of a machine constructed in accordance with my4invention; Fig. 2 is a transverse section, portions thereof along theradial lines 0 to 5, inclusive, being taken in. planes indicated by thecorresponding lines. in Fig. 4; Fig. 3 is adevelo ed elevation showingthe entire circum -erence of the central rotatable portion; Fig. 4 isavertical section through one of the filling devices; Fig. 5 is atransverse section through, the valve of one lillingdevice; Fig. 6 is atransverse section on the line ST6 of Fig. 4; Fig. 7 is a verticalsection through a portion of the lling device 'and the float controllertherefor; Fig. 8 is a transverse section on the line 8 8 of Fig. 7, andFig. 9 is a View similar to Fig. 6, but showing the parts renderedinoperative by the absence of a bottle.4 4

chine illustrated in the accompanying drawings are supported in a mainframe A, wlnch latter is in the form of a verticallydisposed cylinderhaving openings'in the I a base frame A1 and is secured thereto in A anysuitable manner, as, for instance, by bolts or screws A2. The base frameis supported by suitable legs A3, and itserves to support a main driveshaft B, having on one end thereof a pulley B1 and on the opposite endthereof, a bevel latter meshes with a bevel gear Bcarried by avertically-disposed shaft Bt.` Parallel to this shaft. VB4 is t-he mainupright revolving shaft C, which carries the filling mechanism. Theshaft is driven from the shaft B4L by suitable gearing, including a gearwheely Cl secured to the shaft C, adjacent its lower end and meshingwith a pinionB5 carried by the shaft B4. The main upright shaft C isprovided with a sleeve keyed thereto, which sleeve at its lower end isprovided with outwardly-extending fingers or projections C2,constituting a spider for moving the bottles and above this spider areoutwardly-extending flanges C3, C4 and C5, which may all be formedintegral or may be formed of separate members rigidly secured together,and all rotatable with the shaft C. The sleeve, fian'ges and spider arepreferably held from rotation by means of a key C, and there are heldagainst vertical movement by means of a shoulder C7 adjacent the upperend of the shaft. These parts are supported at their lower ends by a nutC8, threaded on the shaft C below the top of the base frame A1, and theshaft itself and the parts carried thereby may be supported-verticallyby any form of thrust bearing, as, for instance, a plate C".

My'invention is adaptable for use in filling any kind of container, butjthe specific form illustrated is especially designed for fillingbottles. The empty bottles are delivered to the machine by an endlessbelt W, having a portion thereof extending substantially tangentially ofthe machine and this same belt serves to convey the filled bottles fromthe machine. The belt is disposed upon approximately the samfehorizontal level as the upper surface of the base frame 4A1 and thespiders on both moving arms are gear B2, which disposed at such anelevation above the base frame'that the/bottles may be enga-ged by gsaid shaft. As the gear wheels C1 and D2v intermesh, the peripheralspeeds of the spiders C2 and D will be substantially the same, and thearms are so disposed that the spider D will operate to engage withsuccessive bottles on the belt and deliver them to the spacesintermediate the successive arms of the spider C2. For retransferringthe bottles from the spider C2 to the belt at the delivery sideof themachine, I substantially duplicate the spider D2. This secondtransferring means includes a spider E, mounted on a shaft E1, whichlatter is driven by the engagement of thegear wheel C1 with a gear E2adjacent the lower end of said shaft. In connection with the threespiders and the belt, I preferably employ suitable guides fprmaintaining the bottles in their proper positions. These include curvedplates, bars, or strips, E3 for engaging with the outer sidesof thebottles and holding them in engagement with the spiders D and E whilethe bottles are being transferred, and a curved bar E4 for retaining thebottles bev tween the arms of the spider C2. The guides Es may extendalong the outer edge of the belt and yadditional guides E may bedisposed adjacent the inner edges of the belt to -form channels ofwhich. the belt constitutes the bottoms. As both the spiders D and E aredriven from the gear wheel C1 and the power is delivered directly to thelatter, it will be evident that the parts passage F3 in alinement withthe shaft C's always maintain a constant relative speed.

lThe bottles when delivered along the belt W may be carelessly placedthereon at varying distances apart, and ,it isy desirable thattheirpositions be controlled and regulated as they approach the spiderD, so that they will enter the proper recesses between the arms of saidspider. this, Ifprovide bottle-spacing and controlling mechanism,including-a series of lingers or prongs L. Each of these lingers has itsfree end extending out over the belt W and into the path ofthe-bottlesdelivered along.

said belt. `The fingers are mounted on suit'- able pivot pins supportedin a frame L1,

"and the fingers are normally held resiliently in the path of thebottles lby suitable springs L2 encircling said pivot pins. All of thefingers are connected together by a link L7, so that a movement of onenger insures a For accomplishing j movement of each and all of thefingers. The first fingerof the series is controlled by an arm L4,pivoted on-apin L5v in the frame L1 and rigid with an arm L extendinginto .the path of a series of pins L3 carried by. the gear wheel D2. Thepins L are dis osed in such relationship to the arms o the lspider D, i,that each time an arm of the spider comes to the proper position, thetingers L are wlthdrawn and each bottle on the belt is permitted toadvance one step and the lirst bo-ttle of the series will entertheproper position in the spider and be delivered to the filling machine.

After the bottles leave the spider DV and are moved about the circularpath by the spider C2, the filling mechanism comes into operation anddelivers to each'bottle a measured quantity of liquid. The fillingmechanism, as previously stated, is rotated with the main shaft C, andlthere are as vmany separate filling mechanisms as there are spaces inthe spider C2 to receive bottles. In the present instance, I employeight separate filling mechanisms, and, therefore, all of the partsrotatable with the shaft C are provided eight times. A detaildescription of one of these filling mechanisms is thought to besuiicient, reference .being had particularly to Fig. 4. Above the shaftC and in vertical alinement with each of the several bottles carriedbythe spider C2, I provide a. plurality of measuring chambers F, eachpreferably in the form ofl a cylinder and having valve-controlledcommunication with a' main supply pipe and with a delivery pipe to thebottle. These measuring chambers are preferably formed' in a separatemember secured 'to the flange C5 by bolts F2, which flange forms aflooring or bottom for each ofthe measuring chambers and also for anannular chamber F1,disposed within the annular row of measuring chambersF. The annular chamber F1 is in open communication with acentrally-disposed' conduit or and rotatable therewith. At the upperend, the conduit F3 is connected to a general` supply pipe Fl, by meansof an elbow F8, and t-he joint between the elbow and the conduit- Fs isrendered substantially liquid-tight by a packing F7. The pipe F4contains a controlling valve FE and the elbow carries an air escape pipeF, through which'the air withinfthe annular chamber F1 and theconnecting parts may escape while the machine is being vfilled for thefirst time.

Within each measuri'n'er chamber or cylinder F, there is 'mounte avertically-movable piston G. Extending upwardly from. the piston is apiston rod G1 connected to a guide rod G2 Vextending substantiallyparallel toy the piston rod and adjacent the outer surfaceA of thecylinder. Intermediate its ends, the guide rod carries a roller G3 esame"andv the amount of liquid delivered to the measuring chamber and forcedfrom Ithere to the bottle, is determined. The ,guide rod G2 has ahorizontally-disposed portion extending from the piston-rod G1 to themain portion of the guide, and this-horizontallydisposed portion isslidable upon a rod G5,

which 'serves to prevent the guide rod from moving in 'other than avertical direction. The rod G5 is supported at its upper end by anoutwardly-extending bracket rG", carried by an annular iange G", securedto the member forming the several measuring chambers. This iian'ge maybe held by bolts Gr8 and its central portion may constitute a gland orpacking'about the central conduit F3. The ange G7, also preferablycarries a small adjustable slide G9, adjacent the upperendof thecylinder -and adapted to engage withthe piston and serve as astop tolimit the upward movement of the latter and prevent its displacementfrom the cylinder, as well as control the maximum quantity of liquidwhich can be forcedinto the measuring chamber.

-For controlling the inhausting and exhausting of the liquid, I providea valve H, directly below each measuring chamber. The valve is holldwand provided with ports b, b, which may register with correspondingports in the'bottom of the supply chamber F1 and .the measuring chamberF, when the valve is in one position, and Ahaving 'ports a, a, which mayregister with the -I'ggrt in the bottom ofthe measuring chamr and withthe inlet end of the supply pipe .to the bottle, when the valve is in a.second position. The valve 4is radially disposed in respect to the mainshaft C, and 'at the outer end of the valve'stem, I provide a collar'terminating in two oppositelydisposed studs lor projections H1 and H2,by 'means of' which the collar andthe valve are 'rotated at the propertime: The main frame ofthe' machine carries two stationary studs orprojections H3 and'H, so disposed that 'as the shaft C and the partscarried thereby rotate, the projections H1 will engage with the singleprojection I-I3 at one part 'of the circuit and rotate the valve in" onedirection, and each projection H2 will l engage with the projection I-I4at a different portion of thecircuit, to rotate the valve in theopposite direction. The two projectionsl H3 and I-I4 are atapproximately diametric'al'ly opposite points on the machine, so 'thatthe valve will be moved twice, once in each direction during a vcompleterotation of the shaft C. The projections H4 serve to turnt-he valve, tobring the ports 7), into operation and permit the measuring chamber tobe filled, while the projection H3 serves to bring the ports a, a `intooperation and permit the bottle to be lilled from the measuring chamber.When the ports b, b are in operation, the liquid delivered underpressure will enter the measuring chamber and raise the piston G intoengagement with the stop G", where it will remain until the valve isagain rotated.

v The liquid is conveyed'from the valve H to the bottle through a pipeformed of two telescoping sections, the lower section I being verticallymovable, and the upper section I1 being rigid with the flanges CA1 4andC5. The lower or movable pipe section I carries a bracket I2, verticallyadjustable in respect thereto and normally rigid therewith, and upon anoutwardly-extending stud or pivot integral with the bracket is a rollerI3. This roller engages with a fixed camway I4, which by` its engagementwith the roller I3 controls the reciprocating move ment of the pipe I.To prevent rotation of the pipe I, I provide a stationary rod I5, alongwhich the bracket VI2 may slide, but which serves to prevent rotation ofthe bracket about the pipe. At the lower end `of the stationary pipesection I1, a suitable packing I is employed, to prevent leakage betweenthe two pipes, and at the lower end of the lower pipe section IT is .avalve I2, serving to close openings I in the sides of the pipe, andnormally held over said openings by asuitable coil spring Is. Thetension of the spring is such that, together with atmospheric pressure,it will close the lower end of the 'pipe as soon as the valve H isclosed, and thus the liquid remaining in the pipe will be prevented fromescaping after the bottle is removed.

Toinsure the proper positioning of the bottle mouth in regard to thepipe I, the flange C2 preferably carries a curved collar K, shown insection in Fig. 2. The main frame carries a guide K1 above the spider I)and so disposed as to force the bottle neck into the curved collar andretain it downwardly into the mouth of thebottle.

A In order to prevent the opening of the valve and the delivery ofliquid in c'ase `no bottle should arrive along the belt in time to bereceived in the proper position in the spider C2, I provide mechanismcontrolled bv the presence of a bottle for throwing cer.- tain elementsofthe mechanism in operation only in case a bottle is in the properposition.

'This mechanism includes a depending plate or `bar M. hinged at itsupper end to a bracket M1, rigidly secured to the main frame A at theentrance side thereof and at approximately the level of the flange C3,as indicated particularly in Fig.v 4. A vertically-disposed rod M2 ismounted intermediate the plate M and the frame and extends vmechanismwill operate in its through' the bracket M1. This rod carries an arm M3,engaging .with the rear side of the plate M, and also carries a secondvarm M4 at its u per end. vThe arm M4 is connected by a linl; Mi to 'aplate M, which carries a portion of the camways G* and It, and theprojection H3. The late is supported by two bell crank levers 47, eachof which is fulcrumed on the main frame and has its opposite endsprojecting through the frame and connected together by a link M8. Aspiral spring M9 on the rod M2, servesto hold the plate M in the path ofthe bottles as they are moved along by the spider C2, and it alsoservesto hold the plate M closely adjacent the inner surface of the mainframe A, as indicated in Fig. 9. This brings portions of the camways G4and I* and the projection II3 out of thepath of the rollers '"Gr3 and I3'and the valves, so that in case no bottle is in position inthe spider,the operating parts of the lling mechanism remain stationary during therotation of the shaft C. When a bottle is in position, the plate M ismoved outwardly and the parts are broughtl to the position indicatedparticularly in Figs. 4 and 6. Now, when 'the shaft C is rotated, the

proper sequence and the pipe I will be projected into the bott-le, thevalve H will be rotated and the piston G will be forced downwardly todeliver the liquid.

The mechanism above described. serves to fill each and all ofthe bottleswith the same quantity of liquid, said quantity being determined by thepositions of the several stops G9. In lilling bottles withcertain kindsof liquid, it is desirable that the neck of the bottle should remainempty for a definite distance down from the mout-h, lrrespective of theheight of the particular bottle.

As is well known, bottles 'of the same kind vary slightly in height, andin order to provide for this variation in height, and at the sameltimeleave an empty space of definite height in the neck of the bottle,I so construct the mechanism, as to deliver to each bottle apredetermined quantity of liquid which will be more than suiiicient tofill the bottle, and then to withdraw from the mouth of the bott-le asuiicient quantity of liquid to lower the level to a definite distancebelow the mouth of the bottle. For accomplishing this purpose, I providethe mechanism, a portion of which is illustrated particularly in Figs.l7 and 8. The liange C3, adjacent each pipe I, carries afloat N, open atits lower end and -supported within a casing N1. The iloatis slightlysmaller than the casing and is held concentric therewith by longi#tudinally-disposed ridges4 or anges N2, as

illustrated in Fig. 8. The upper end of the ioat carries a rod N3,extending through an opening in the upper end of the casing N1,

and a packing ring N* is provided which will engage with a Bange on theinner' surface of the top of the casing, to seal the lattersubstantially air-tight when the float is raised toits limiting`position.. The'bottle as it is filled is automatically raised intoengagement with a packing ring N5, encircling the pipe I but spacedtherefrom, and the interiors of the casing and ioat are both in opencommunication with the interior of the bottle througha. passage N6 andthe annular passage between the pipe I and the packing ring N 5. Thestem N3 of the floatl is provided with a spring N7, the j with thepacking rings Nl5 during the time t-he last portion of the liquid isdelivered to the bottle and a portion thereof withdrawn, I provide alifter O, shown particularly in Fig. 3. This lifter is pivoted to twoarms O1, 4O2, hinged to brackets O3, O",-carried by the frame A, and inconnection with one of these is a spiral sprin O5, for raising thelifter and the bottle. ne end of the spring is connected to a rod O,provided with a nut O7, whereby the tension of the spring may be readilyadjustable. The gear wheel C1 of the shaft carries a series of cams O9on its under side and adjacent its eriphery and the lifter O carriesa'roller (l lying in the path of thesecams. The spring O5 normally holdsthe lifter in raised position, but as each bottle approaches the lifter,the latter-is depressed by the engagemen of a cam O9 with the roller O8,so that the bottle may readily pass on to the lifter, whereuponthe-lifter is immediately released, and the bottle raised upwardly intoengagement with the packing ring N5. In order to retain the bottle inits ',raised position for a short time after it leaves the lifter and toaccurately and yieldingly return it to its lowered position, I employ lalight -bar O10, pressed upwardly by a coil spring O11 at the pivotalsupport of the bar. v

As different bottles have slight-ly diii'erent forms and no liquid canescape either from the bottle or past the float N, I so construct aportion of the camway G4, which forces downwardly the pistons in theseveral measuring chambers, that the piston when it reachesapproximately the Y end of its stroke, will be resiliently operated. Foraccomplishing this, I provide the construction illustratedparticularlyi'n` Fig. 3, which includes a vertically-movable bar I,having a camway section P1 at its lower end and substantially inalinement with the main portion of the camway G4. The bar P is mounteddirectly above the lifter O and is f so `supported upon two'f pivotedarmsIv2 and P3 carried by the'- tramex A. One of these arms 1s connectedto a spring P4, whereby the` camway section Pi is normally or'ced down-5 ward-ly, and the 'opposite end. of this spring may be connected to airod P5, having a nut I6 to facilitate the adust-ment-of the tensionvAfter they neck of the bottle has been completely filled mechanism comesinto opera tion or withdrawing acertain amount of 'liquidto lowerthelevel to a predetermined distance below the mouth. This mechanism, asshown particularl in Fig. 4, includes a suction-'piston R, adjacent-eachpipe I1 and vertiiza-lly movable with: a small c linder R1 carried by"the' ainge C5. Each piston is secured to a pistbn rod R2, and eachpiston rod' has a bracket R3, clamped thereto and carrying a roller R4.This roller may en- Gage with acamway R5, securedl to the main Irame A.The upper 'end of the` cylinder R1 is in open communication withtheupper end 'of' the pipe I1, and the camway 1s so disposed that thepiston is drawn downwardl tdwithdraw liquid `from the'upp'er endg o .thepipe Il after the valve H is closed and while the' pipe I isbeing liftedout of the bottle.A ToA prevent rotationof the piston rod' R2, al guiderod R (see Fig. 2) is preferably ernployed, and is so disposed as toextend through a portion of the bracket R3. Each suction piston R is soconstructed that it works' equally well in both directions, so thatduring thedownward movement of the piston, liquid is positively suckedout of the pipe I1, while upon the return movement 0T the piston', the.liquid vis positively'forced into said pipe. l

In Fig. 3, I haveillustra'teda developedexterior view of themachie withthe casing removed, so' that `the course of the bottles and the stepsin' the operation mary be more clearly disclosed. The machine is capableof receiving eight bottles at one time, but as there is always one spacevacant at the en# trance side of the machine, the filling operation iscarriedi on in seven steps or stages, numbered as I to VII,inclusivegwin Fig. 3.

in the position indicated on the line I4 of Fig. 3. The valve I-I is insuchl a position that the liquid isA entering the filling chamber andthe piston G and the' roller G3 have moved to their upward limiting'position.

tated to the position indicated' on line II,

rIfhe bottle enters the machine with the parts The roller R4 immediatelyengages the camway R5,= to raise the piston R', and the roller I3engages the camway I4t to lower the tube I into the bottle. When the..parts have' rothe valve H is rotated by the engagement of the studI H3with the projection H.1 and the' roller G3 comes into' engagement withthe cain G4 preparatory to forcing the piston G downwardly. The pipe Icontinues its downward movement until the position indicated inf lineIII is reached, and the piston G and roller Gf conti-nue their downwardmovement until the position indicatedin line VI is reached. The pipe Irea/'chesiits lowermost position shortly after the valveI'I is closedand as the liquid enters the bottle the pipe is graduallywithdrawnuntili thev entire operation is completed and the bottle reaches theposition indicated on the line VII. The piston R remains stationaryiii-'omv the time the valve H is opened to'llthe botv` tle until aftertheA valve isclosedl.' As soon` as the valve is closed, whichv takesplac'e when the bottle is in the osition' indicated o'n the line VI, thelifter comes into-operation to raise the bottle into; engagement withthe. packing N and the piston` It is brought downward as the pipe isbrought' upward,- so that a predetermined quantity 9 E of liquid iswithdrawn -from the bottle;-

E'ach and all of the bottles as they are fed into the machine and-cometo the position indicated on the line II, contact with. the
